3 OPERATING INSTRUCTIONS
3.1 Initial start-up
3.1.1 Safety precautions
The operator must apply all related safety precautions including
those mentioned in this book.
3.1.2 User manual
Read the "User manual for Elektronikon regulator " to
familiarize yourself with all regulator functions.
3.1.3 Outdoor/altitude operation
If the compressor is installed outdoors or if the air inlet
temperature can be below 0 degrees Celsius, precautions must
be taken. In this case, and also if operating at high altitude,
consult Atlas Copco.
3.1.4 Moving/lifting
The compressor can be moved by a lift truck using the slots in
the frame. Make sure that the forks protrude from the other
side of the frame. The compressor can also be lifted after
inserting beams in the slots. Make sure that the beams cannot
slide and that they protrude from the frame equally. The chains
must be held parallel to the bodywork by chain spreaders in
order not to damage the compressor. The lifting equipment
must be placed in such a way that the compressor will be lifted
perpendicularly. Lift smoothly and avoid twisting.
3.1.5 Initial start-up
1. Consult section 2 for the electric cable size, installation
proposals and dimension drawings.
2. Read the "User manual for Elektronikon
®
regulator" to
familiarize yourself with all regulator functions.
3. A sticker dealing in short with the operation instructions is
delivered with the literature set. Affix the sticker next to
the control panel.
4. Stick labels near the control panel warning the operator that:
- the compressor may automatically restart after voltage
failure
- the compressor is automatically started and stopped
- the compressor may be remotely controlled
5. A number of VCI (Volatile Corrosion Inhibitor) plates are
provided inside the bodywork to protect the compressor
against corrosion. Remove the plates.
